Question / Help Camera not working


New Member
I'm using Firefox Quantum, 63.0.0 64 bit as my browser, on windows 10 os, trying to run a live video on Facebook and can't get the camera to turn on. I get sound, but no video. I've tested the camera in video mode and it works fine. I can do a live video on my desktop version, but that doesn't seem to offer all the functionality when I'm in Firefox. Anyone know what I need to do?

I'm not real computer literate and know just enough to crash my computer from time to time. So make it as simple as you can for me, please and thank you.
